IMPROVEMENT IN FURNlTURE-CASTERS.

Specification forming part of Letters Patent No. 132,066, dated October 8,1872.

- a horn surrounding a boss formed on the under side of a plate, and said plate secured by means of a central screw and the nature of my invention consists in an annular flange or ferrule formed on the upper side of said plate, and fitting in a corresponding groove made in the leg where the caster is applied, said flange or ferrule being on its upper edge provided with pins or teeth to penetrate into the wood, all of which will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a side view of a table-leg with my caster applied; Fig. 2 is vertical section of the caster and lower end of the leg; Fig. 3 is an end view of the leg; and Fig. 4 is an enlarged side view of the boss and plate with the flange or ferrule and pins.

A represents the Wheel pivoted between arms extending from a horn, B, whichsurrounds a boss, G, formed on the under side of a plate, D, and the whole secured to the end of a leg, E, by means of a central screw, G. These parts may all be constructed in any of the known and usual ways for such casters. On the upper side ofthe plate D, and surrounding the central screw-hole, is formed an upward-projecting annular flange or ferrule, a,

which fits in a similar groove, 1), made in theend of the leg E. On the upper edge of the flange or ferrule a are formed upward-projecting pins or teeth it, which enter the wood as the screw G is tightened. The flange or ferrule to, entering the groove b in the leg, prevents the wood from splitting or breaking, and.

also prevents the caster from slipping out in case the screw should get loose. The pins or teeth i '5 entering the wood prevent the plate D from turning.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The annular flange or ferrule a, p rovided with pins or teeth 2' i on its upper edge, and formed on the upper side of the plate D of the caster herein described, to fit in a corresponding groove, 1), on the end of the leg, and the pins or teeth to penetrate into the wood, all substantially as and for, the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 11th day of 7 September, 1872.
